Description

复合结构板 技术领域
本发明涉及一种用于在家具制造业中使用的、由加强件和塑料板件形成的复合结构板。
背景技术
实木板和曲木板是家具制造业常用的材料，比如可以用来制作桌子、椅子的座板和靠背、书架或橱柜的横竖隔板、抽屉板等。但这些材料的使用消耗了大量的木材，而且使用场合和使用寿命也受到一定的限制。
如今，出于保护环境和降低生产成本等目的，越来越多的家具制品使用塑料板来代替木板。塑料板可通过注塑成型或者吹塑成型来制作。注塑成型的塑料板通常仅具有有限的强度。尽管吹塑成型的塑料板外观简洁、易于清洗，但成型的吹塑板也相对较厚。尤其是对于较大的家具产品，吹塑板的生产周期长，生产效率低。另外，较大的吹塑板也需要非常大的模具和用来执行复杂生产工艺的吹塑机。因此，吹塑塑料板的生产成本相对较高。在家具制造中也会使用直接加工成型的金属板。然而，这种经过机加工的金属板的表面颜色和质感单一，使用场合有局限性。
本申请的发明人在其中国发明专利CN 102987726B中公开了一种包括三层结构的桌面板，这三层结构依次为面板、加强板和设置在二者之间的加强框，其中，加强框采用方形横截面的管材弯曲制得，并内撑于在面板与加强板的周边所形成的环形空腔之内，同时与面板、加强板及形成在二者上的上下凸缘重叠之处相配合而实现限位。这种复合板需要分别对面板与加强板的周边进行弯折以由此在二者之间形成环形空腔，随后再将加强框插入空腔内，由此需要三个不同组件的相互配合，从而使得加工过程比较复杂，成本高，而且这三个组件的结合方式在强度上还有待进一步增强。
因此，存在着对于具有更好的强度但却能使加工简化、成本降低并具有较长产品寿命的复合结构板的需求。
发明内容

具体实施方式
本文中任意实施例中涉及方向的描述，例如“上/下”、“左/右”、 “顶部/底部”等等都是为方便进行说明而基于附图本身的方向而言，且不会对本发明形成限制。
在如图1和图2所示的根据本发明的第一实施例中，复合结构板1主要由三个部件构成：正常使用时面向外的面板2，通过粘合剂或可行的其它任意方式与面板固定连结在一起的底板3，以及设置在面板2与底板3的周边部分处的加强件4。
面板2具有基本上位于同一平面的主体部分2c和由该主体部分2c向下弯折形成而围绕在所述主体部分四周的周边部分2a，且面板2具有在正常使用中朝外的上表面和在正常使用中朝内的下表面。底板3上形成有基本上均匀分布的整体成形的多个突起或突起阵列3a，其中，面板2的下表面通过热熔焊而粘附并支撑在多个突起3a的顶面上，而且底板3的周向边缘沿水平方向抵接面板周边部分2a的内表面。优选地，粘合剂被涂覆在突起3a的顶面上，从而与面板2的下表面形成点状的粘结。
面板2可以是吸塑塑料板，或者通过注塑工艺而成型，底板3可以采用与面板相同的成型工艺成型，但有些采用吸塑工艺整体成形。虽然图中所见的底板3上均匀交错地形成有截圆锥形的突起或突起阵列3a，但突起3a的形状、深度或排列方式可以根据实际需求调整变化。
加强件4优选地由金属制成，更优选地由钢制成，但同样也可以由硬质塑料制成，只要其能实现为复合结构板提供增强的强度的目的。
尽管如上所述的复合结构板由三个部件形成，但本申请中仍将所要保护的这种强度得到明显提升并且减少了组成部件数量的复合结构板称为“双层复合结构板”，因为面板2与底板3之间的加强件4实际上仅在复合结构板的周边处与二者相互连接。
图2是图1中的A部的放大图，其中具体显示了加强件4的具体结构以及与面板2与底板3的连接方式。该实施例中的加强件4是横截面为矩形或方形的框架式结构，该框架式结构可以是中空的， 或者说加强件4的截面形状为封闭的框架。面板2的周边部分2a被向下弯折后继续向下延伸，而加强件4的最外侧的垂直边与向下的周边部分2a贴合，其底端沿水平方向向外略微突出形成整体式凸缘4a，面板的向下延伸部分的自由端2b恰好支撑在凸缘4a上，使得所述凸缘4a的末端与延伸部的外表面基本齐平。
更具体地，面板2的由主体部分2c向下弯折形成的周边部分2a沿基本上垂直于面板2的主体部分2c的方向向下延伸成延伸部，加强件4的顶面与面板2的主体部分2c大致平行并且与底板3的下表面抵靠在一起，且加强件4的最外侧的垂直表面与周边部分2a的垂直延伸部的内表面抵靠在一起，而且在该垂直表面的下端向外突出形成凸缘4a，而面板2的延伸部的自由端2b支撑在凸缘4a上。
虽然图2中示出的加强件4的截面呈矩形或方形的形状，然而可以将之视为为了清楚地看到加强件4的位置与构型而放大了比例。实际产品中的加强件4的长宽比可以根据实际设计需要更大或更小。另外，图2中显示的加强件4的截面是封闭的框架式结构，然而在其它实施方式中，加强件4在某其一边缘处可以是断开的，呈现例如背靠背的“双L形”结构。
图2中的加强件4的顶部可以如前所述地、例如通过粘合剂等与底板3固定粘结在一起，也可以通过机械加工的方式与底板3的底面夹紧在一起。。为了更牢靠地使加强件4的最左侧边与面板2的向下延伸的周边部分2a的内表面贴合并保持就位，加强件4的左侧边与面板2的内表面之间同样可以涂覆粘结剂等，并在就位之后通过热熔焊进行固定连接。
图2中还示出底板3的最外侧为不具有突起的平坦部分，而且该部分朝向所述面板2的方向略微向上凹陷，形成底面为平面且宽度大于加强件4的宽度的凹陷部3b，从而加强件4的顶端能够被放置在凹陷部3b内，以使加强件4的顶面与底板3的凹陷部3b的下表面固定连接。此处，固定连接同样可以通过涂覆粘合剂并随后进行热熔焊来实现。
图2中还清楚地示出在加强件4的左下部位形成有凸缘4a，借助该凸缘可以实现加强件4相对于面板2的可靠定位和支撑。
具体的，加强件4具有底端，也即图2中看到的最下侧表面，该最下侧表面与加强件4的同面板2相连接的顶端对置。当完成面板2、底板3和加强件4的组装后，加强件4的最下侧表面将形成双层复合结构板的最底端，该最底端可以例如是完整连贯的加强边框，例如金属边框或硬质塑料边框。还想到，可以是断续的或分段的加强边框，例如金属边框或塑料边框。
加强边框的宽度将远大于面板2的下边缘的宽度，从而不但增强复合结构板的强度，还能兼具支撑复合结构板的作用。此外，加强件4的厚度可以是塑料面板2的厚度的0.2、0.4或者1.0倍。
图3示出了根据本发明的第二实施例，与第一实施例类似的，根据该实施例的复合结构板由三个部件形成，即，正常使用时面向外的面板2、通过粘合剂等可行的其它任意方式与面板2固定连结在一起的底板3，以及至少部分地设置在面板2与底板3之间的加强件4。
在如图3所示的第二实施例中，面板2左右两端各自具有截面为倒立的L形的中空框架结构的加强件4，左侧的加强件4和右侧的加强件4成镜像对称布置，并且，两个加强件4的中的每一者的一条直角边平行顶板2并贴紧顶板2的下表面，并且在相互贴靠的位置可以涂覆粘结剂，并随后通过热熔焊实现进一步的牢固结合。
图4示出了根据本发明的第三实施例，其中，双层复合结构板的各部件的构造、相对位置和连接方式等均与在前述第一、第二实施例中所描述的相同或相似，它们之间主要区别在于以下两方面：
第一，在面板2上或其向外的表面中形成有凹陷部或扣手5，该凹陷部或扣手将位于由复合结构板组装成的家具的最外表面，例如形成于柜子的柜门上，以方便使用者开闭柜门，或者便于抓取复合结构板本身。优选地，扣手5的形状设计符合人体工程学，从而分别使用者操作，由此提升使用者的使用感受。
第二，加强件4的形状呈现为如图3中所示的“L”形，该L形构造的竖向部分和横向部分的比例可以根据实际需求进行调整，例如，竖向部分可以比横向部分更长或更短。亦即在该实施例中，加强件4是横截面为L形的框架式结构，并且所述L形的最外侧的垂直边底端向外突出形成凸缘4a，面板2的周边部分2a向下延伸的自由端2b将稳定地支撑在凸缘4a上。
更具体地，加强件4是横截面为直立的大致为L形的中空框架式结构4，该L形中空框架式结构的一条垂直边位于靠近底板3上的突起3a的最内侧且垂直于面板2，该L形中空框架式结构的位于外侧的台阶形状表面的最下端向外突出形成凸缘4a，面板2的周边部分2a沿基本上垂直于主体部分2c的方向向下连续弯折成台阶状延伸部，而且该台阶状部分的形状与所述L形框架式结构的台阶形表面的形状相匹配。面板2的台阶状延伸部分的自由端2b稳定地支撑在所述凸缘4a上。
在图4所示的第三实施例中，面板2在其边缘处、也即周边部分2a的形状与第一和第二实施例中不同。从图4中可以清楚地看到，面板的周边部分2a的形状与加强件4的形状适配，即，周边部分2a贴合着加强件4的L形构造而同样呈现为L形的结构。通过这种形状上的相互配合，不仅使面板2的造型富于变化，更加美观，而且进一步实现了面板2与加强件4的固定结合，从而增强了复合结构板的整体强度。当然，面板2也可以采取第一实施例和第二实施例所述的构造，即，只弯折一次。
图5和图6示出了根据本发明的第四实施例，与前述第一、第二、第三实施例类似，根据该第四实施例的复合结构板同样由三个部件构成，即，正常使用时面向外的面板2、通过粘合剂等可行的其它任意方式与面板固定连结在一起的底板3，以及至少部分地设置在面板2与底板3之间的加强件4。
从图5中可见，左侧的加强件4和右侧的加强件4可以根据实际情况分别采取横截面形状不同的两种加强件来与面板2和底板3 进行连接。相应地，面板2的形状也可以随着加强件4构型的变化而适应性匹配。这样便于根据不同的需求实现不同方式的组装。
根据第四实施例的双层复合结构板各部件的构造、相对位置和连接方式、加强件4的宽度、厚度等，均与前述第一实施例中的相关描述相同。
第四实施例与第一实施例的明显区别之一在于面板2与底板3之间是紧密贴靠还是有一定的距离。在图2所示的第一实施例中，可以看到在加强件4上方，在面板2的主体部分2c与底板3之间存在相对较大的间隔，其间可以进一步设置一个或多个横向的或与加强件4的纵向平行延伸的加强肋，以进一步增强复合结构板的强度。而在第二至第四实施例中，可以看到面板2的主体部分2c与底板3的外侧周边紧密贴合，即在底板3与加强件4相连接的位置，面板、底板与加强件之间不存在任何间隙。
此外，图11示出了根据本发明的第五实施例，如图所示，加强件4的截面呈现为背靠背的“双L形”结构，该双L形共享同一竖边5，该竖边5沿着与主体部分2基本垂直的方向延伸至与面板2的下表面抵接，且该竖边贴靠周边部分2a的内表面延伸并位于该周边部分的内侧，位于外侧的L形结构的横向向外延伸的底边围绕周边部分2a的延伸部的最下端向上弯折，从而包绕周边部分2a的底侧边缘。
作为一种优选的实施方式，该第五实施例中背靠背的双L形结构的竖边的末端沿着基本上平行于面板2的主体部分2c的方向向内水平弯折以紧紧地按压在底板3的边缘上。
通过使外侧的L形结构的横向向外延伸的底边紧密包绕面板2的周边部分2a的底侧边缘的至少一部分来进一步实现二者之间的固定连接。这可以通过任意已知的工艺或借助任意已知的工具来完成。被包绕的区域在竖向上例如占据面板2的周边部分2a的五分之一、四分之一、三分之一等等；在侧向上、即沿着面板2的周向，可以包绕面板的周边部分2a的整个边缘或者断续地包绕面板的周边部分 2a的边缘。
在以上各任意实施例中，凸缘4a向外延伸的末端可以与周向部分2a的延伸部的外表面基本平齐。优选地，所形成的凸缘4a将相对于周向部分2a的延伸部略微向外偏置，从而使得所获得的复合结构板具有较平缓的外边缘，由此可以避免划伤使用者或刮破衣物等。
同样地，在加强件4的截面为双L形结构的第五实施例中，外侧L形的形成包绕周边部分2a的下边缘的横向边也优选地是平缓的或具有圆滑的拐角，以避免划伤使用者或刮破衣物等。
图7A和7B示意性地示出了据本发明的优选实施方式的复合结构板的加强件的截面视图，其中加强件的凸缘4a的下侧还可设置有自其向下延伸的翼部4b。
图8示出了双层复合结构板的面板2的顶面或最外表面1a，其可以是平坦的规整表面，并用作例如图9、图10所示的柜子的顶部表面1a。优选地由塑料制成的面板2的顶面1a可以附着模仿天然木材或石材的纹理的贴面，使得复合结构板具有模拟天然材料的外观。复合结构板的表面还可以具有利用吸塑成型成各种形状的凹槽，以使其看起来更加自然、美观。在此情况下，加强件4的互补表面可以模制有对应的凹槽来支撑吸塑塑料面板和/或底板，同时增加复合结构板的强度。其中，加强件4可以经拉伸及卷边或弯曲成型。
图9、图10示出由根据本申请的任意实施例的复合结构板组装而成的柜子。复合结构板1可以用作家具、例如柜子的顶部板、底部板、侧板等。
在各实施方式中，塑料面板和/或底板可以是吸塑或注塑塑料强件可以是成型或拉伸加强件。
本申请中就一个实施方式描述的特征可应用在其他实施方式中。上面描述的用于柜子的复合结构板当然也可以用于桌子、架子、靠背、书架或橱柜的隔板、抽屉和其他家具部件。
图12-15示例性地示出了由本发明的复合结构板组装而成的箱子200，其包括箱盖210、底板220以及多块侧板230，这些侧板230 首尾依次拼装连接，相邻的两个侧板230之间形成拼接缝240。所述侧板230包括连接在一起的面板231及加强件232，所述加强件232沿着所述面板231四周的边缘设置，首尾相邻的两个侧板230当中，一侧板230的加强件232向外延伸出翼部2321，翼部2321是竖向设置的长条结构，所述翼部2321从外部遮住二侧板230之间的拼接缝240。
优选地，所述面板231的四周朝内弯折形成折边2311，所述折边2311从外侧围住所述加强件232，所述加强件232上设有凸缘2322，所述凸缘2322压住所述折边2311的边沿。通过所述加强件232上的凸缘2322将面板231的折边2311压住，使得面板231更加紧密与加强件232贴合为一体，使得整体的结构更加紧凑稳固，翼部2321在凸缘2322下侧自其向下延伸。
优选地，箱子包括前后左右四块侧板230，四块侧板230围成矩形框结构，所述箱盖210铰接在矩形框结构上并用于盖住上面的开口，所述底板220盖住矩形框结构下面的开口。前后两侧板230夹持住左右两侧板230，前后侧板230的加强件232上形成所述翼部2321，即前、后侧板230的加强件232的左右两侧都设有翼部2321。
